Re: Question on Wave number frequency spectra

The MJO scripts were written to do what the referenced article
suggested. Beyond that, **there is no support**.

[1]
Switching the AXIS is 'easy'[attached]

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl"
load "./mjo_wavenum_freq_season_plot.ncl_gibies"

Possibly, but it would require work and **I can offer no support**.

You could extract "mjo_wavenum_freq_season" from diagnostics_cam.ncl

%> vi $NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl

create a separate file and modify it.
Also, the
http://www.ncl.ucar.edu/Document/Functions/Diagnostics/resolveWavesHayashi.shtml

which is used is pretty much expecting (time,lon)

Good luck
